Bug #78387 [NEW]: references won't work for coalesce result

From: mpatnode at popsugar dot com Operating system: any PHP version: 7.4.0beta2 Package: Arrays related Bug Type: Bug Bug description:references won't work for coalesce result Description: ------------ Not sure if this is a bug, but the behavior is unexpected. If a coalesce result is used in a foreach with a reference, the reference is ignored. If it's not legal syntax, then the reference should generate a warning or notice. Behaved the same on every PHP version I tested. Test script: --------------- $foo = ['bar1' => 1, 'bar2' => 2]; foreach ($foo ?? [] as &$bar) { $bar = 3; } var_dump($foo) Expected result: ---------------- array(2) { 'bar1' => int(3) 'bar2' => int(3) } Actual result: -------------- array(2) { 'bar1' => int(1) 'bar2' => int(2) } -- Edit bug report at https://bugs.php.net/bug.php?id=78387&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78387&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78387&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78387&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78387&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78387&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78387&r=support Expected behavior: https://bugs.php.net/fix.php?id=78387&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78387&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78387&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78387&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78387&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78387&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78387&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78387&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78387&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78387&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78387&r=mysqlcfg
